I should give an explanation - I've setup clementine to use the system default languageOf course I could set it to English - and I've done it already.I just was curious why an qt based application wouldn't do it automaticallyI had another qt based app (I can't remember which one) where I had to set it by handEvery other app I'm using uses en for menus/messages and de for currency, page size etc.pp

Automatic setups are a matter of currency (not the money type, but more akin to how up-to-date they be!)--so the problem for any developer in English say, is how to manage translations and how well to do them; if they are not multilingual then knowing if a translated menu is correct or not will be a problem

So they may only offer their native language as the structure for their application, and perhaps then depend on volunteers to provide menu translations etc..--computer automatic methods may not be satisfactory for that person, they have to decide..

This is why you sometimes find programs you may want to use or try out to be only available in another language, such as German, Russian, Spanish, French etc..

Thanks for replying!I think it's not a matter of translations. I live in germany but want all messages/menus to be in en_USclementine has a complete translation - this is my setup:LANG=en_US.UTF-8LC_ADDRESS=de_DE.UTF-8LC_IDENTIFICATION=de_DE.UTF-8LC_MEASUREMENT=de_DE.UTF-8LC_MONETARY=de_DE.UTF-8LC_NAME=de_DE.UTF-8LC_NUMERIC=de_DE.UTF-8LC_PAPER=de_DE.UTF-8LC_TELEPHONE=de_DE.UTF-8LC_TIME=de_DE.UTF-8

For every other app, the system set language is recognized as en_US but not (some) qt based apps.
